Abstract (en)
[origin: GB2260966A] A microprocessor controlled volumetric infusion pump is set as to volume and rate of infusion by two digipots (shaft encoders) each having sixteen detented positioned in 360 degrees. The microprocessor is programmed such that the extent to which the parameter is changed for a given rotation of its setting digipot depends on the speed with which the digipot is rotated. For slow or normal rotation, unit change in parameter is produced for each detented position traversed. Faster rotation causes the setting to jump from one to the next of a series of preselected preferred settings, irrespective of the number of detented positions traversed. The direction of rotation determines whether the setting increases or decreases.
